Morphology and bacterial colonisation of tooth/ceramic restoration interface after different cement excess removal techniques

Influences of multiple firings and aging on surface roughness, strength and hardness of veneering ceramics for zirconia frameworks

“…In clinical practice, decreasing the surface roughness of dental materials exposed to the oral environment has many positive effects. It not only prevents the accumulation of plaque and the colonization and adhesion of bacteria, but may also decrease the incidence of chipping and the abrasiveness of the opposing surfaces [5,13,[44][45][46].…”

Impact of excess cement removal on vertical misfit and cement line quality in onlays

“…However, finishing and polishing procedures removed these defects partly or totally. Imperfections left at the cementation line, restorative material or dental surface can facilitate the bacterial biofilm adhesion, consequently an adequate excess cement removal and a judicious finishing and polishing steps are required for obtaining a smoother cementation margin [4,17,[21][22][23]] to avoid bacterial colonization, recurrent caries, periodontal disease [15,16] increasing the longevity of ceramics restorations.…”

“…If this procedure is concluded after cement setting, grooves and roughness (due to material hardness) are produced, which enables bacteria adhesion, especially critical at the proximal faces at gingival or subgingival area [4,17,[21][22][23]. Therefore, if cement excess was removed while the resin cement is capable to flow, a smoother surface could be achieved because the material could be removed using a spatula.…”

“…Therefore, if cement excess was removed while the resin cement is capable to flow, a smoother surface could be achieved because the material could be removed using a spatula. In addition, is easier to remove non-polymerized cement form the proximal areal [21] reducing the chance of scratches formation on the restoration or tooth surfaces.…”

Influence of thickness, color, and polishing process of ethylene‐vinyl‐acetate sheets on surface roughness and microorganism adhesion

“…Therefore, a colorless material cannot reach the same level of flexibility as a colored material, especially if the heating times are kept constant, and this can interfere with the level of adaptation during the manufacturing process . As for the polishing procedure, it is known that a poorly polished surface can induce the accumulation of microorganisms due to the greater roughness …”
